CVE-2024-31081

一、漏洞信息
 漏洞编号：[CVE-2024-31081](https://nvd.nist.gov/vuln/detail/CVE-2024-31081)
 漏洞归属组件：[xorg-x11-server-xwayland](https://gitee.com/src-openeuler/xorg-x11-server-xwayland)
 漏洞归属的版本：22.1.2
 CVSS V3.0分值：
  BaseScore：7.3 High
  Vector：CVSS：3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:H
 漏洞简述：
  A heap-based buffer over-read vulnerability was found in the X.org server s ProcXIPassiveGrabDevice() function. This issue occurs when byte-swapped length values are used in replies, potentially leading to memory leakage and segmentation faults, particularly when triggered by a client with a different endianness. This vulnerability could be exploited by an attacker to cause the X server to read heap memory values and then transmit them back to the client until encountering an unmapped page, resulting in a crash. Despite the attacker s inability to control the specific memory copied into the replies, the small length values typically stored in a 32-bit integer can result in significant attempted out-of-bounds reads.
